In this article I would like to share the procedure to change the separate Master Page for a SharePoint subsite.
Master Pages
Master Pages provide the look and feel that you want for all of the pages in your site. By changing the styles or content of the Master Page, you can quickly customize the appearance of an entire site.
Procedure to change the Master Page on a Subsite
Use the following procedure to change the Master Page.
Step 1
Open your site, then click on the settings and from the drop down choose the site settings as shown below:
Step 2
When you click on the site settings, you will be navigated to the site settings page as shown below.
NOTE: By default the “Master Page” option is not available in the SharePoint site. You should activate the “SharePoint Server publishing feature” in your site for “Master Page settings”. Go to the “Manage site features” on your site settings, then activate the publishing feature.
Step 3
Then click on the Master Page on the site settings page from the “look and feel” section as shown below.
Step 4
When you select the “Master Page”, you will get the site Master Page settings as shown below.
Step 5
On the Site Setting page you have the following two options:
- Inherit site Master Page from parent of this site If you checked this option parent site Master Page will be applied to your site
- Specify a mast page to be used by tis site and all sites that inherit from it if you checked this you can set the separate Master Page for your subsite.
Here I've selected “Specify a master page to be used by this site and all sites that inherit from it”.
Step 6
You can select the Master Page from drop down as shown below.
NOTE: If you have published custom Master Pages then those Master Page will also be available on the drop down. Here I've selected the “oslo” master for my sub site.
Step 7
After you selected the Master Page, click on the “ok” button to save your changes as shown below.
“Finally selected Master Page will be applied on your sub site successfully”.
Summary
In this article we explored how to apply the separate Master Page for a subsite.
